In Patient 1, who was 40 years old and had a cerebellar hemangioblastoma, the P86L missense heterozygous germline mutation was identified in exon 1. The DNA analysis of close relatives did not show affected subjects. This patient was recommended for VHL disease surveillance protocols (15) (Table 4) and developed a retinal hemangioblastoma 4 years after diagnosis.
